What Is the Life Expectancy of People with Untreated Sleep Apnea?

Sleep apnea is a sleep disorder that affects millions of people worldwide. It is a serious condition that can lead to complications, particularly in those who do not seek treatment. In this article, we will explore the connection between sleep apnea and life expectancy, including its types, symptoms, and treatment options, to help readers understand how this condition can affect their health and well-being.

Understanding Sleep Apnea

What is Sleep Apnea?

Sleep apnea is a condition in which a person’s breathing repeatedly stops and starts during sleep. This happens because the muscles in the back of the throat fail to keep the airway open, causing the individual to wake up frequently throughout the night. There are different types of sleep apnea, but the most common is obstructive sleep apnea (OSA).

OSA occurs when the muscles in the back of the throat relax too much during sleep, causing the airway to become blocked. This can lead to a decrease in the amount of oxygen in the blood, which can have serious health consequences if left untreated.

Types of Sleep Apnea

Aside from OSA, there are two other types of sleep apnea: central sleep apnea (CSA) and complex sleep apnea syndrome (COMPAS). CSA occurs when the brain fails to send the correct signals to the muscles that control breathing, while COMPAS is a combination of both OSA and CSA.

CSA is less common than OSA, and is often associated with other medical conditions such as heart failure or stroke. COMPAS is a newer diagnosis, and is still being studied to determine the best treatment options.

Symptoms and Warning Signs

The symptoms of sleep apnea can vary from person to person, but some common signs include loud snoring, gasping or choking during sleep, and excessive daytime sleepiness. It can also cause headaches, irritability, and memory problems, among other symptoms.

If left untreated, sleep apnea can lead to more serious health problems such as high blood pressure, heart disease, and stroke. It can also increase the risk of accidents due to daytime sleepiness.

Treatment Options

Treatment for sleep apnea depends on the severity of the condition. Mild cases may be treated with lifestyle changes such as weight loss, avoiding alcohol and sedatives before bed, and sleeping on your side instead of your back. Moderate to severe cases may require the use of a continuous positive airway pressure (CPAP) machine, which delivers air pressure to keep the airway open during sleep.

In some cases, surgery may be necessary to remove excess tissue from the back of the throat or to reposition the jaw. It is important to talk to your doctor about the best treatment options for your individual needs.

The Connection Between Sleep Apnea and Life Expectancy

How Sleep Apnea Affects the Body

Untreated sleep apnea can have serious consequences. When an individual stops breathing repeatedly during sleep, their oxygen levels can drop, which can put a strain on the heart and other vital organs. This can lead to high blood pressure, heart disease, stroke, and other complications that can affect their overall health and well-being.

However, the impact of sleep apnea goes beyond just physical health. It can also affect a person’s mental health, causing them to experience mood swings, anxiety, and irritability. Additionally, sleep apnea can make it difficult for individuals to concentrate and perform well at work or school.

Long-term Health Risks of Untreated Sleep Apnea

Studies have shown that untreated sleep apnea can lead to a shorter life expectancy. It increases the risk of developing other health conditions such as diabetes, obesity, and depression, which can further impact a person’s quality of life and lifespan.

For example, individuals with sleep apnea are at a higher risk of developing type 2 diabetes. This is because sleep apnea can affect the body’s ability to regulate glucose levels, leading to insulin resistance and eventually diabetes. In addition, sleep apnea can contribute to weight gain, which is also a risk factor for diabetes.

Furthermore, sleep apnea has been linked to an increased risk of heart disease and stroke. This is because the repeated drops in oxygen levels during sleep can cause damage to the blood vessels and increase inflammation in the body. Over time, this can lead to a buildup of plaque in the arteries, increasing the risk of heart attack and stroke.

Depression is another potential long-term consequence of untreated sleep apnea. Chronic sleep deprivation can have a negative impact on mood and emotional well-being, leading to feelings of sadness, hopelessness, and anxiety. This can make it difficult for individuals to enjoy life and engage in activities they once found pleasurable.

In conclusion, sleep apnea is a serious condition that can have a significant impact on a person’s health and well-being. If left untreated, it can increase the risk of developing other health conditions and lead to a shorter life expectancy. It is important for individuals who suspect they may have sleep apnea to seek medical attention and explore treatment options to improve their overall health and quality of life.

Studies on Life Expectancy in People with Untreated Sleep Apnea

Key Findings and Statistics

Research has shown that individuals with untreated sleep apnea have a higher risk of premature death. A study conducted by the American Academy of Sleep Medicine found that people with severe sleep apnea were three times more likely to die prematurely than those without the condition. Another study revealed that men with sleep apnea were twice as likely to die from any cause compared to men without it.

It is important to note that sleep apnea is a serious medical condition that can have a significant impact on a person’s quality of life. People with sleep apnea often experience daytime fatigue, difficulty concentrating, and mood disturbances. In addition, untreated sleep apnea can lead to a range of other health problems, including high blood pressure, heart disease, and stroke.

One possible reason for the increased risk of mortality in people with untreated sleep apnea is the impact it can have on the cardiovascular system. When a person with sleep apnea stops breathing during the night, their blood oxygen levels can drop, which puts stress on the heart. Over time, this can lead to the development of cardiovascular disease and ultimately increase the risk of premature death.

Limitations and Considerations

While these studies suggest a correlation between untreated sleep apnea and a higher risk of mortality, it is important to note that causality cannot always be inferred. There may be other factors contributing to the increased risk of death, such as preexisting medical conditions or lifestyle factors, which should be taken into consideration.

It is also important to note that there are effective treatments available for sleep apnea, including continuous positive airway pressure (CPAP) therapy, which can help to improve sleep quality and reduce the risk of associated health problems. If you suspect that you or a loved one may have sleep apnea, it is important to speak with a healthcare professional for an accurate diagnosis and appropriate treatment.

Treatment Options for Sleep Apnea

Lifestyle Changes

For mild to moderate sleep apnea, implementing lifestyle changes such as losing weight, avoiding alcohol and smoking, and improving sleep hygiene may be enough to alleviate symptoms and improve overall health.

Continuous Positive Airway Pressure (CPAP) Therapy

CPAP therapy is a common treatment for moderate to severe sleep apnea. It involves wearing a mask over the nose or mouth connected to a machine that delivers a constant stream of air pressure, helping to keep the airway open during sleep.

Oral Appliances and Surgery

Oral appliances and surgery may also be options for some individuals, depending on the severity of their sleep apnea. Oral appliances can help to keep the airway open during sleep, while surgery can be used to remove excess tissue or correct structural abnormalities that are causing the breathing problems.

Improving Life Expectancy with Sleep Apnea Management

The Importance of Early Diagnosis

Diagnosing and treating sleep apnea early is crucial in improving life expectancy. Seeking medical attention for persistent snoring, gasping, or choking during sleep can lead to early detection and appropriate treatment, reducing the risk of complications and improving overall health.

Success Stories and Testimonials

Many individuals who have received treatment for sleep apnea report improved quality of life, including reduced snoring, better sleep, and increased energy levels. Managing sleep apnea can improve overall health and well-being, leading to a longer, healthier life.


Sleep apnea is a serious condition that can affect the quality of life and lifespan of those who suffer from it. While untreated sleep apnea can lead to long-term health risks, early diagnosis and appropriate treatment can help individuals alleviate symptoms and improve their overall health and well-being, leading to a longer, healthier life.
